Didroxyprogesterone tablets are progesterone, which is a fetus-protecting drug. If used in normal doses during pregnancy, they will not affect the pregnant woman and will not affect the fetus. Generally, it is because of the low progesterone level in pregnant women’s bodies that they can use drospirenone tablets to supplement progesterone and achieve the effect of fetus preservation, which can also regulate the secretion of hormones in pregnant women’s bodies and therefore will not affect them. However, if the progesterone level in the body is not low, there is no need to take this drug under normal circumstances. If taken in excessive doses, it may cause bleeding or vomiting, abdominal pain, and prolonged use of dydrogesterone tablets may also affect the function of the liver, or cause breast pain, itchy skin, headache, or skin allergy or hives.
